DOOR- BELL.

SPECIFICATION forming part of Letters Patent No. 460,114, datedSeptember 29, 1891. Appiicaion nea July 24, 1890. sean No. 359,726. uiomodel.)

To all whom it may concern:

Be it known that I, GEORGE A. CoLToN, a citizen of the United States,residing at Chicago, in the county of Cook, State of Illinois, haveinvented certain new and useful Improvements in Door-Bells, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to cert-ain new and useful improvements inalarms; and it has for its object, amongothers, to provide an improveddevice of this character Which may be so connected as to form aburglar-alarm, and in which notice is given when the spring needsWinding. The warning-card may be thrown out at any point; but the top ispreferred, as by this arrangement it will be returned by its own weight.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,Which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure l is a central section through myimproved bell, shown in operative position. Fig. 2 is a face view withthe bell removed and parts broken away. Fig. 3 is a View from thereverse side with parts removed. Fig. 4 is a plan of the alarm-train.Fig. 5 is a detail, partly in section and partly in side elevation,whichWill be hereinafter more particularly referred to.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the detail of the drawings by letter, A represents apart to which the device is secured. It may be a door orlany other partof a house or structure.

B designates a circular plate, having surrounding ange a, as shown bestin Fig. l, so as to provide a space between the plate and the part A forthe movement of an arm and the Warning-card, as seen in said Fig. l.This plate is formed with suitable holes a for the reception of screwsor other securing means ft2, by which it is held in position. The innerface of the plate is strengthened by radial ribs as, through which theholes a are made, as

shown in Fig. o. The under side of this plate B is provided centrallywith a depression b, which forms a chamber bf upon the outer face forthe reception of the spring, a circular flange b2 upon the outer face ofthe plate forming the surrounding walls of said chamber. The bottom ofthis chamber is provided with a transverse slot b3, and upon the upperside is out away, as shown at b4, to provide for the reception of theWarning-card C, as shown in Figs. 1 and 3.

D is an arbor extending from the plate B, and at its outer endscrew-threaded, `as shown at d, being bored for the reception of apushpin D', as shown best in Fig. 1.

D2 is a sleeve surrounding this arbor, and D3 is the Winding-lever,provided with suitable handle CZ and having a hub d2, which surroundsthe sleeve D and is secured thereto in any suitable manner-as, forinstance, by the set-screw cl3, as shown in Fig. 1. This lever isprovided with an offset d4, as shown, so as to bring the lever betweenthe spring and train, as will be understood from Fig. l, the lever beingdesigned to be revolved between the plate B and the bell, as hereinafterdescribed.

E is a spring arranged Within the chamber of the plate B, and secured atone end to the sleeve D2, as shown at e, and its other end suitablyconnected to the ange b2. F is a segmental plate pivoted at f to theplate B and near its free end provided with a lateral pin f', whichWorks in an elongated transverse slot f2 of the warning-card C, saidcard being preferably halved out to receive the extension f3 of thesegmental arm, as shown in Fig. l, which serves to guide the same. Uponthe upper portion of this warning-card I affix the words Needs winding,as shown iu Fig. 2. This segmental plate is provided with a lug f4,extending at right angles thereto and working in a recess f5 of theflange Z22 ,of the plate B, said lug being arranged in the path of thespring, so that as the latter unwinds it will force the segmental platearound on its pivot and by reason of the engagement of the pin thereofwith the elongated slot of the warning-plate thus gradually raise thesame until the words Needs winding are displayed. As the spring is Woundup, the Warning-plate falls to its normal position by its own weight. Onthe winding-lever I may affix letters or words lVind here, as shown inFig. 2.

G is a bracket secured to the plate B upon the inner face thereof andprovided with a boss g, fitted into an opening or socket therefor in thepart A, as shown in Fig. l, and through this boss Ais an opening inwhich works loosely7 the pin G', designed to be actuated by apush-button G2, of any preferred form, working through aretaining-socket G3, which may be as ornamental in design as desired.

Conned Within a suitable case H, secured upon the arbor D, is a suitabletrain of gearing, which may be of any preferred construction, providedwith ordinary escapement h, arranged to vibrate the bell-hammer h', ar-

ranged to sound an alarm upon the bell H', which is secured upon ascrew-threaded piece i h2 on the plate H2, which is secured to the outerface of the case H. The main gearwheel I of this train is secured on thesleeve D2, as shown in Fig. l, and is provided with,

an ordinary ratchet. (Not shown.)

at the other end provided with an inwardlyprojecting pin j', which isdesigned to engage the arms J2 of the escapement and hold the samenormally inactive.

The operation will be readily understood. With the spring wound up andthe pin of the spring-plate J holding the train from motion, when thepush-button is pushed open the sliding pin moves the spring-plateJoutward and disengages its pin j from the alarm-train, when said trainis set in motion and the bellhammer vibrated and the alarm sounded. Asthe spring unwinds it. contacts with the lug f4 of the segmental plateand gradually forces the Warning-card C outward, giving notice that thedevice will soon need winding or is nearly run down. It not attended ioand `Wound up after the warning-card is shown,

if the bell is rung it will continue to strike until the spring is rundown.

I may sometimes arrange -the device to form a burglar-alarm, and forthis purpose I employ a bar L, which is designed to work in the slot b2of the plate B and having one end extended beyond the case, where'it maybe connected in any suitable manner by cords or chains connected in thewell-known bell-crank and wire way and lead across doors or windows, sothat any strain on the connection will actuate the rod or bar and causethe bell to ring. The inner end of the bar L is formed with a camportion l, as seen in Fig. 5, which, as the said bar is actuated,engages the push-pin D and actuates the bar J and sets the bell toringing. The bar L is provided with a lateral lu g Z,which is arrangedin the path of the unwindin g spring, as shown in Fig. 5, so that theunwinding of the spring continues to force the bar outward and keep thebar .I stretched voutward rom engagement with the alarm-train. Aspring Lmay be employed to normally keep the bar L in position, as shown in Fig.3. I may sometimes employ a pin M, acting against the inner end of thebar L and arranged to actuate the same from the opposite side. While Ido not design ordinarily to employ all of these different forms ofoperating the device in connection with a single bell, having' simplyillustrated them to show some of the different forms, yet they may beall connected to the one bell if occasion should require.

It will be Observed thatthe operating parts are all supported andoperated upon the one arbor. I preferably place upon the windinglever anarrow or other indicating-mark to designate the direction in which itshould be turned.

What I claim as new is l. In a door-bell of the class described, thecombination, with the warning-card and with the guides therefor,arranged radially to the axis of the spring, and said card provided withtransverse slot, of the spring and the pivoted arm arranged in the pathot' and adapted to be moved on its pivot by contact of the spring as itunwinds and having a pin J is a plate secured at one end, as at j, and

working in the transverse slot of the Warningcard, substantially asshown and described.
